A kind of supporting equipment for open TBM anti-collapse equipment

Abstract

The invention relates to a supporting device for an open type TBM anti-collapse equipment, including an upper anti-collapse cover, a side anti-collapse cover, a connecting plate, a connecting rod, a tunneling casing and a supporting mechanism; in the present invention, the traditional welding type is fixed, It is changed to a detachable type, and in the existing equipment, multi-heel screws are used for fixing, which can not only achieve an effective fixing effect, but also facilitate the replacement and maintenance of the upper anti-collapse cover and the side anti-collapse cover. The operation effect, specifically, the setting of the combined structure of the support rod, the support block and the support groove is used to support the installation of the connecting rod, and through the combination of the fixed cover plate, the fixed screw, the No. 1 threaded hole and the No. 2 threaded hole, the The connecting rod is fixed in the support groove.

Description

technical field [0001] The invention relates to the technical field of tunneling equipment, in particular to a supporting device for an open TBM anti-collapse device. Background technique [0002] The TBM roadheader is mainly suitable for the construction of long-distance hard rock geological tunnels, but the probability that the long-distance tunnel geology is single hard rock geology is almost zero, and often encounters unforeseen weaknesses that are not suitable for TBM excavation during the TBM excavation process. Strata, such as faults, soft soil, and mud-and-rock strata, etc., when encountering such strata, the weak surrounding rock exposed at the tail of the TBM shield cannot be supported in time, which will lead to frequent collapses, which pose a great safety risk. Falling objects scattered in the hole required a lot of manual cleaning, resulting in very slow or even impossible excavation of the TBM. [0003] The open type TBM is a type of roadheader, which is an a...

AI Technical Summary

Problems solved by technology

Due to the long time-consuming, low efficiency, high cost and difficult construction of conventional reinforcement methods, the advantages of high tunneling efficiency of TBM equipment cannot be fully utilized. Therefore, an upper anti-collapse cover and a side anti-collapse cover are installed behind the cutter head of the roadheader. Through the combination of the upper anti-collapse cover and the side anti-collapse cover, it can prevent the tunnel from collapsing

[0006] However, in the existing design process, the fixing process of the upper anti-collapse cover and the side anti-collapse cover is welded, which increases labor costs and time costs for later maintenance and replacement, thereby increasing production investment invisibly
